Spray polyurethane foam (SPF) is made on the jobsite by combining polymeric methylene-diphenyl diisocyanate (pMDI/MDI or A-side) with an equal volume of a polyol blend (B-side). Sides A and B react and expand at the point of application in the building envelope to form polyurethane foam. The formed-in-place SPF provides both thermal insulation and air sealing to the building. Four classes of SPF with varying performances and applications are assessed in this declaration. Closed-cell spray foam for roofing systems (Roofing) is used on the external surface of low slope roofs. Its higher density provides additional compressive strength needed for roofing applications. Closed-cell, or medium density foam, (ccSPF) provides a water-resistant insulation, air-sealing, water vapor control and delivers added structural performance to the building envelope. Open-cell low-density spray foam (ocSPF) provides insulation and air sealing. SPF can be further categorized based on the type of blowing agent utilized in the product. OcSPF uses a reactive blowing agent, water. Added water in the B-side reacts with A-side isocyanates to create CO2 gas. CcSPF and roofing foams use physical blowing agents that transform into a gas during installation due to the exothermic foam reaction that occurs. These physical blowing agents are either hydrofluorocarbons (HFC) or hydrofluoroolefins (HFO). Please note that this declaration only covers HFO formulations for ccSPFand roofing products, as well as reactive (water) blowing agent ocSPF. A complete list of all SPF manufacturers and product covered by this declaration is provided in the Appendix.
